Solving for y. write the following equations in slope-intercept form.

1) 3x-2y= -16
2) 9x - 7y = -7
3) x - 3y = 6

1)   3x - 2y = -16          Subtract 3x from both sides
           -2y = -3x - 16   Divide both sides by -2
               y = x + 8

2) 9x - 7y = -7          Subtact 9x from both sides
           -7y = -8x - 7   Divide both sides by -7
              y =  + 1

3) x - 3y = 6          Subtract x from both sides
        -3y = -x + 6   Divide both sides by -3
           y =  - 2
